Question | Answer |
---|---|
Which network device can be used to eliminate collisions on an Ethernet network? | switch |
True or False? VLANs improve network performance by segmenting broadcast domains. | true |
True or False? VLANs can improve security by isolating sensitive data from the rest of the network. | true |
Which type of VLAN is assigned to 802.1Q trunk ports to carry untagged traffic? | native |
True or False? It is a best practice to configure the native VLAN as VLAN 1. | false |
Which is true of VLAN 1? (Choose all that apply.) | all switch ports are assigned to VLAN 1 by default The native VLAN is VLAN 1 by default the management VLAN is VLAN 1 by default VLAN 1 cannot be renamed or deleted |
Refer to the exhibit Question 1 Topology. PC1 sends an ARP broadcast frame. Which PC will receive the ARP broadcast frame? | PC4 |
Refer to the exhibit Question 2 Topology. PC2 sends an ARP broadcast frame. Which PCs will receive the ARP broadcast frame? (Choose all that apply.) | PC3 PC4 PC6 |
Refer to the exhibit Question 3 Topology. PC3 sends an ARP broadcast frame. Which PC will receive the ARP broadcast frame? | PC5 |
True or false? DTP is an open standard IEEE protocol that specifies auto negotiation of switch trunk links. | false |
What is the default switchport mode for Cisco Catalyst switches? | dynamic auto |
True or false? Two switchports on a link both configured as dynamic auto will successfully negotiate a trunk. | false |
Which two DTP modes will form a trunk with an interface that is configured as dynamic auto? (Choose two.) | trunk dynamic desirable |
What happens to a port that is associated with VLAN 10 when the administrator deletes VLAN 10 from the switch? | the port becomes inactive |
In which memory location are the VLAN configurations of normal range VLANs stored on a Catalyst switch? | flash |
An administrator is investigating a failure on a trunk link between a Cisco switch and a switch from another vendor. After a few show commands, the administrator notices that the switches are not negotiating a trunk. | switches from other vendors do not support DTP |
What is the purpose of the vlan.dat file on a switch? | it holds the VLAN database |
What is the purpose of setting the native VLAN separate from data VLANs? | A separate VLAN should be used to carry uncommon untagged frames to avoid bandwidth contention on data VLANs |
When a Cisco switch receives untagged frames on a 802.1Q trunk port, which VLAN ID is the traffic switched to by default? | native VLAN ID |
A network administrator is determining the best placement of VLAN trunk links. Which two types of point-to-point connections utilize VLAN trunking? (Choose two.) | between two switches that utilize multiple VLANs between a switch and a server that has an 802.1Q NIC |
What are three primary benefits of using VLANs? (Choose three.) | cost reduction security improved IT staff efficiency |
On a Cisco switch, where is extended range VLAN information stored? | running configuration file |
In which location are the normal range VLANs stored on a Cisco switch by default? | flash memory |
Which distinct type of VLAN is used by an administrator to access and configure a switch? | management VLAN |
For what reason would a network administrator use the show interfaces trunk command on a switch? | to view the native VLAN |
Where is the vlan.dat file stored on a switch? | in flash memory |
If an organization is changing to include Cisco IP phones in its network, what design feature must be considered to ensure voice quality? | a separate VLAN is needed for voice traffic |
A Cisco switch currently allows traffic tagged with VLANs 10 and 20 across trunk port Fa0/5. What is the effect of issuing a switchport trunk allowed vlan 30 command on Fa0/5? | it allows only VLAN 30 on Fa0/5 |
